well i do know this..look inside the drivers door for RPO codes...i haven't heard of a Z28 with a 2.73 rear end but if you see
GU4 = 3.08
GU5 = 3.23
GU6 = 3.42
that is...even if the car still has the sticker inside the door [img]smile.gif[/img]

If you want 3.42's, then you want a rear from a 6spd car. I believe it was only '93 that actually had the option in a 6spd for 2.73's, all the rest came standard with 3.42's.
Automatic Z28's/TA's had 2.73's standard and an option for 3.23's

are you talking about the GU codes?
If so then yes, they are correct for all years.
